L & S Mono Scan Converter
 |
The Mono Scan Converter is used in the Mono Pulse Antenna Feed networks to acquire the signal and produce Amplitude Modulating signal (SUM+ difference signal), which performs “delta over sigma” normalization functions and according to which the antenna movement is controlled. The L-band unit accepts the ‘L’ band input 1435 to 1545 MHz and ‘S’ band unit accepts input frequency from 2200 to 2400 MHz signal from the transmitting source and an A.M modulation is imposed (SUM+ difference signal) over the received signal strength of the mono pulse antenna. This is done at a 500 Hz rate so that the output is modulated at 500 Hz rate.
